In a hurry? Use the Project Preview Window quick guide instead.
You'll check almost every edit in the Project Preview Window, because it plays your PowerDirector timeline the way it will export. When a busy part of the timeline stutters, PowerDirector can render it once so playback runs smoothly.
A Tour of the Project Preview Window

Two Preview Windows, Two Jobs
PowerDirector has two preview windows, and it helps to know which one you're looking at. The Media Library Preview Window plays a single clip you've clicked in the library. The Project Preview Window plays your timeline, with everything stacked together the way it will export.
Play, Pause, and Step
Click the play or pause button under the bottom left corner of the preview. Or tap the spacebar. Click Stop, right next to the play button, to send the playhead back to the very start of the timeline.
For finer work, click the two step buttons next to the play and stop buttons to nudge the playhead one frame at a time. That's how you land a cut on an exact frame.
Set the Project Aspect Ratio
Set the aspect ratio before you get deep into an edit, because it decides the shape of what you export. Click the ratio button at the bottom right of the preview and pick one: 16:9, 9:16, 1:1, 4:3, 4:5, 21:9, or 360. Landscape video is almost always 16:9, and you'll want 9:16 for phone-first video.
Switch to 9:16 and the preview reshapes straight away, so you can see how your framing holds up before you commit to it.
Fill the Screen
To judge small details, click Full Screen View, just left of the ratio button, to blow the preview up to the whole display. To come back to editing, click the X at the right end of the playback bar. Or press F to switch in and out of full screen.
Switch the Layout
Click the Layout button under the preview, just left of Full Screen View, to give the preview one of three shapes. Which one suits you depends mostly on what you're cutting:
| Mode | Best for |
|---|---|
| Landscape | The default. Standard 16:9 edits, with the preview across the top |
| Portrait | Vertical 9:16 edits. The window stretches from the top of the screen to the bottom |
| Floating | Detaching the preview so you can put it anywhere, including on a second monitor |
Floated the window and want it back? Click Dock Preview Window at its top right and it snaps home.
Zoom the Preview
Zooming the preview is handy when you're lining up a title or checking a mask edge. Click the magnifying glass under the preview to scale the image up or down. Or hover over the preview and scroll with Ctrl held down to zoom without leaving the mouse.
Choose a Preview Quality
Click the menu icon at the bottom right of the preview and choose Preview Quality to set the resolution PowerDirector renders the preview at. Higher settings look sharper but ask more of your computer. Lower the setting if playback stutters, and raise it if your computer has room to spare.
Keep an Eye on the Volume Meter
In the same menu, choose Show Preview Volume Meter. A live level meter appears next to the playback buttons under the preview, so you can see how loud your audio is.
Stay out of the red. Levels that sit in the red band for any length of time clip the audio, and that distortion is baked into your export. Pull the volume down until the meter peaks below it.
Render Preview When Playback Stutters
For smooth playback on a busy stretch of timeline, click the Render Preview button next to the camera icon under the preview. PowerDirector renders that section once into a temporary file, so playback runs smoothly from then on.
Take a Snapshot
Spotted a frame you want as a still, maybe for a thumbnail? Park the playhead on it and click the camera icon at the bottom right of the preview. In the Save As window, choose a folder and click Save.
The image also lands in My Media, so you can drag it straight back onto the timeline without hunting for the file.
We tested these steps in PowerDirector 365 version 23.3 on Windows.
Don't have PowerDirector yet? Play, step a single frame, set the aspect ratio, grab a still. These are the controls you reach for in your first hour of editing.

The Media Library Preview Window plays one clip you've selected in the library, on its own. The Project Preview Window plays your timeline, with every track, title, and effect combined the way they will export.
No. Preview resolution only affects what you see while editing. Your export settings decide what gets exported, so a lower preview quality is a safe way to keep editing smooth on a slower machine.
You choose the folder when you save one. The same image is also added to My Media, so it's ready to drop onto the timeline without importing it again.
